I SWING Application filed April 27,

Thisinvention relates to new and useful improvements in a swing joint. 1

One ob 'cct of the invention is to provide a joint of the character described, specially designed for use in connecting two sections of pipe together so to permit one of said sections to swing, as on a hinge joint, wlth respect to the other. This type of joint is specially adapted for use in connection with tanks, or. reservoirs, for connecting the inner section of the inlet, or outlet pipe, to the inlet or outlet line proper. This inner section is pivoted to swing up or down in a vertical plane, so that any selected stratum of the flu1d in the tank may be drawn off, as hereinafter explained, and the specific type of joint herein described has been found to be very efficient for connecting said inner section to the main inlet, or outlet.

Another object of-the invention is to provide a swing joint of the character described, which is of Very compact structure and composed of few parts and consequently may be cheaply produced and easily assembled and is very eflicient in use.

With the above and other objects in view this invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, where- 111 Figure 1 shows a plan view of the joint, partly in section, and showing the connecting yoke carried by the swing pipe section.

Figure 2 shows a longitudinal sectional view of the T with the tubular trunnions mounted therein in position for assembly with the yoke.

Figure 3 shows a side view, partly in section, of the joint, and

Figure 4 shows a vertical sectional view of a tank showing the discharge line and the swinging inner section thereof.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 designates a tank and the numeral 2 designates an inlet or outlet line leading from the bottom thereof. Connected to the inner end of this line 2 there is a vertical swinging section 3. This section is connected to the line 2 by means of the swing joint, des ignated as a whole by the numeral 4, which is supported on a suitable platform 5. The cable 6 is connected, at one end, to the free JOINT.

end of the section 3 and passes over 7, fixed to the side of the tank, near its top, and at its other end is connected to a suitable Windlass, as 8.

The free end of the section 3 may be so disposed as to draw off, or discharge the top stratum of oil, or may be lowered, through the Windlass 8, to draw off or discharge near the bottom or any intermediate stratum.

The swing joint 4,.includes a tubular yoke 9 which is formed of one piece and is of a general arcuate contour. Intermediate its ends this yoke has a suitable flanged opening 10 and the yoke is suitably bolted to the flanged end 11, of the pipe 2 so as to align said pipe with the opening 10. The free ends of the arms of this yoke are turned inwardly and formed with the aligned facing bearings as 12, 12.

The numeral 13 designates the tubular T adapted to be fitted closely between the facing ends of the arms of the yoke 9, as shown in Figures 1 and 3. The respective ends of the T 13 form the bearings 14, 14, which align with the corresponding bearings 12, 12, when the joint is assembled, and there are tubular trunnions l5, fitted into these respective aligned bearings, one on each side, so as to break the joints between the T and the corresponding ends of the yoke arms. These trunnions may be held in place by suitable bolts, as 16, or if desired, each trunnion may be driven into one of said adjacent bearings and have a running fit in the other hearing.

The T has the flanged tapped hole 17 intermediate its ends into which the adjacent end of the section 3 may be threaded.

In assembling the joint the T 13 may be disposed between the bearings 12 and the trunnions 15 then inserted through the opening 17 and then moved into position in the bearings 14 and 12 and secured therein by the set bolt 16, or the trunnions may be assembled with the T, with their outer ends flush with the outer ends of the T, as disclosed in Figure 2 and the T then inserted between the ends of the yoke and the trunnions then moved into position in the adjacent bearings 14 and 12, and secured therein as above stated.

What I claim is 1. A joint for connecting two pipe sections and including a tubular one piece yoke of a general arcuate contour and having its free ends turned into alignment and formed with facing bearings spaced apart, said yoke having an opening intermediate its ends for the the pulley connection of a pipe thereto, a tubular T fitted between said yoke bearings and whose ends abut the corresponding yoke ends and are formed with bearings which align with the corresponding yoke bearings, said T having an intermediate opening for the connection of a pipe thereto, tubular trunnions fitted into said respective adjacent bearings and breaking the joints between them, each trunnion being of such size as to permit its insertion through the T opening, and being of uniform exterior diameter to permit its endwise movement through a T-bearing and into the corresponding yoke bearin 2. A joint for connecting two pipe sections and including a tubular yoke whose walls are of integral one piece structure and of a general arcuate contour and having its free ends turned into alignment and formed with facing bearings spaced apart, said yoke having 2 an opening intermediate its ends for the connection of a pipe thereto, a tubular T fitted between said yoke bearings and whose ends abut the corresponding yoke ends and are formed with bearings which align with the cone-'25 sponding yoke bearings, said T having an intermediate opening for the connection of a pipe thereto, tubular trunnions fitted into said respective adjacent bearings and breaking the joints between them, each trunnionbe- 30 In testimony whereof I have signed my 35 name to this specification.
